Demand Management Stage Gates: Build a Decision Funnel

Why Intake Chaos Hurts

Most PMOs start with good intentions: capture ideas, evaluate them, pick the best. But without structure, intake becomes a flood. Urgent requests bypass strategy. Governance turns political. The result? A portfolio that’s reactive, not strategic.

Stage Gates fix this. They create a transparent, auditable path from idea to approval—so you can say “yes” to the right work and “no” with confidence. Our Demand Management Solution shows how to make this the foundation of portfolio success.

Learn how to build a “front door” and you will have the foundation for a successful PMO operation. Not only will this help you take control of your portfolio, it will also pave the way for better Project Prioritization.

What are Stage Gates in Demand Management?

Stage Gates are checkpoints in your intake process where ideas are reviewed against agreed criteria before moving forward:

  • Control flow (prevent overload)
  • Enforce governance (reduce politics)
  • Support compliance (check-list of must have data & approvals)
  • Improve data quality (so decisions aren’t guesswork)

This makes Stage Gates a mix of data collection, formal sign-off and best practice, the concept being that by having them integrated into one process it provides transparency and consistency without duplication.

Ideation: The Bedrock of Demand Management

Your best ideas often live on the frontline, where savings, process fixes, and customer “hacks” show up first:

  • Make ideation effortless: one simple, always-on intake form anyone can use.
  • Remove fear of “bad ideas”: lightweight capture, quick triage, fast feedback loop.
  • AI assist: De-duplicate ideas, cluster themes, and draft summaries for different audiences.
  • Communicate the strategy: “We need to save / “We need to grow” / “We need to accelerate” – make it a challenge to solve with collective energy.

A well-structured Demand Management process is a funnel for ideas. By having a good process for prioritization, it means you can broaden the intake process at the top because you can handle the incoming demand effectively.

A Practical Stage-Gate Model

Stage gates must be customised with the right terminology and the right steps, but there are themes we recommend as a place to start:

Gate 0: Ideation

  • Goal: Get ideas in quickly with minimal friction.
  • Inputs: Short description, sponsor, rough benefit.
  • AI assist: Auto de-dupe, tag by theme, suggest similar ideas.

Gate 1: Initiation

  • Goal: Quickly process incoming projects for maximum efficiency.
  • Inputs: High level AHP scoring for Strategic Alignment and Risk Modelling for feasiblity to filter out weak proposals, or ideas that are not ready for detailed review. Key for building stakeholder engagement early in the proposal.
  • Triage: Fast Track urgent requirements (Eisenhower Matrix) / flag mandatory work to access “Gate Lite” route directly to Gate 3.

Gate 2: Business Case

  • Goal: Build forecasts for projects, to estimate costs, resource requirements and benefits, alongside risk assessment and mitigations.
  • Method: Validate AHP model scores with reference to specific benefits in the business case. Forecast resource using templates, or high-level estimates.
  • Constraint Based Planning: Generate scenarios based on maximizing value for given resource limits. Identify projects to progress for next round of detailed planning.

Gate 3: Planning & Commitment

  • Goal: Progress projects to Work in Progress and get going.
  • Resourcing: Build out detailed Work Breakdown & allocate named resources.
  • Governance: Portfolio board signs off, sponsor commit to benefits case.

Gate 4: Execution Control

  • Goal: Escalate challenges via status updates and risk register. Track benefits confidence and key milestones.
  • Milestone Funding: Use milestones to release funding, enabling portfolio controls to step-in if project value looks at risk.
  • Project Cadence: Keep focus on speed if you are targeting throughput as a KPI. Reclaim contingency for other projects wherever possible.

Gate 5: Closure & Benefits Realization

  • Goal: Enforce discipline of lessons learned and track project through adoption to benefits, with a Benefits Tracker baked into Governance.
  • Sponsorship: Ensure accountability for adoption and benefits realization.
  • Demonstrate Value: Celebrate wins – results & cadence of project, positive impact of demand management approach.

Put simply, Stage Gates are the backbone of portfolio governance that should connect project selection through to a cycle of continuous improvement and ongoing narrative on benefits.

Stage Gates + Prioritization = Process

Stage Gates are ideal for implementing a prioritization process. Here’s why:

  • Collect the data you need for review as part of a process, building muscle memory for how to score projects.
  • Apply gating factors to filter out non-starters early.
  • Create parallel flows through one “front door,” triaging to the right sub-portfolio, e.g.:
    • Eisenhower matrix for urgency
    • Mandatory model for “must-do” projects
    • Light-touch route for low-value requests
  • Apply tests for risk and value at the right points; quantifying both enables data-led decisions.
  • Integrate resource availability into approvals to avoid over-commitment (this is where many failures start).
  • Avoid approving projects on financials alone when no resources are available.
  • Add time nuance to approval: “Approved to Start” vs “Approved (start later)” for focus and transparency.

In plain English, prioritization is critical to portfolio success, and Demand Management is how prioritization is baked into your operating model.

Why Phasing Matters

Phased approvals let you keep control of projects without micro-managing every decision:

  • Fund early research so you can right size your long-term pipeline.
  • Explore innovation and R&D ideas without blowing the portfolio.
  • Make informed go/no-go calls at each stage.
  • Keep alert to spending and progress for Work in Progress: cutting back on “zombie” projects may be how you accelerate delivery for high value work.
  • Reflect your R&D process into your governance structure so finance, PMO and innovation work together with shared Stage Gates.

The key is that projects are not simple entities. They have a defined start and end (according to the PMI definition) but what goes in-between is varies greatly.

Governance = Trust and Speed via a Kanban

When you’re managing a portfolio of projects it’s important to have the rules of engagement clearly set out:

  • Roles: Who owns each gate? (PMO, business sponsor, portfolio board).
  • Criteria: Published and agreed upfront.
  • Transparency: Document decisions and rationale.
  • Automate approvals: Workflow sign-off, notifications, SLA timers, and audit trails.
  • Authority levels: Build rules into stage-gates
  • There is a danger of acquiring the “template police” so don’t go overboard

Better still bake all this into software, so doing the right thing is also the easiest option. This is where a Portfolio Kanban board adds value as a single source of truth.

Business Case: Define Benefits Before You Start

The Business Case should be the “Golden Thread” that ties proposal, to delivery to implementation. Use Stage Gates to develop it:

  • Benefits defined upfront: owners, measures, baseline.
  • Evidence over slides: structured data, not vague PPT promises.
  • Accountability: Link benefits to selection criteria and post-initiation checkpoints.
  • Evolve incrementally: The Business Case as a living document not a fixed hurdle.

Nobody expects the pre-approval business case to exactly reflect the end results; the point is that should be the start of a journey and not just a one-time hurdle to get funded.

AI: Practical Help, Not Hype

AI can provide practical support for many elements of the stage-gating process. The key point is that the structure inherent in the stage gates makes AI practical, as it can be trained on specific tasks relevant to the maturity of the project:

  • De-duplication and clustering
  • Chasing data and compliance milestones
  • Document for different audiences
  • Prioritization support
  • Continuous learning from outcomes

Through putting in place the core discipline of Stage Gates you are more likely to succeed with AI, as it adds critical structure to your data that gives LLMs the signals they need to provide useful support.

Metrics That Matter

Building a stage-gate system will help a PMO define success metrics for their portfolio. For example:

  • Gate cycle time: Speed of progress through stage gate - make “decision latency” a KPI.
  • Portfolio mix: Project type by gate – link to strategic alignment and risk to see what’s coming.
  • Benefits Realization: In Closure, capture the outcomes, tracking end results to business case as metric for successful delivery.

PMOs must be prepared to justify their existence. Being able to show what’s happening in a clear way is a great start but being able to then show how things are performing, improving and delivering benefits is a critical next step to this base.

When to Automate – the dangers of Excel

Spreadsheets break at scale. A dedicated software platform gives you assurance and saves you valuable time:

  • Build Stage Gates into Portfolio Kanban, with bespoke process for each sub-portfolio.
  • Implement prioritization for best-in-class project scoring using a criteria model - we recommend Analytic Hierarchy Process (AHP).
  • Collaborate-at-scale with Business Case submissions and team scoring.
  • Automate approvals, audit trails and dashboards.
  • Real-time status and alerts give transparency to stakeholders.
  • Assurance of database model, proving auditability, security and a platform for AI-enabled innovation.

Some PMOs with smaller portfolios are fine in spreadsheets – the point is to recognise when your “free” solution is costing you more than the price of a fit-for-purpose solution.

FAQ: Stage Gates for Demand Management

1. What are stage gates in demand management?

Stage gates are structured checkpoints in the intake process where ideas are reviewed against agreed criteria before moving forward. They help control flow, enforce governance, and improve decision quality.

2. Why keep gates after project initiation?

Because business cases can erode over time. Post-initiation gates (as Steve Jenner advocates) allow you to re-validate benefits, confirm continued strategic fit, and stop sunk-cost drift.

3. How do stage gates and AHP work together?

Stage gates define when decisions happen; AHP defines how to make them fair, transparent, and auditable by converting strategy into weighted criteria and structured scoring.

4. Is prioritization just about funding?

No—prioritization also allocates scarce skills and capacity. A project with funding but no people won’t deliver value.

5. Why is ideation important?

Ideation is the bedrock of demand management. Easy access for frontline staff unlocks practical savings and customer service improvements that leadership might miss.

6. How does AI help in demand management?

AI can de-duplicate ideas, cluster themes, draft documentation for different audiences, and even support prioritization by flagging gaps or suggesting initial scores.

7. What’s the role of a portfolio Kanban?

Mapping stage gates to a Kanban board gives you a single visual truth, enforces WIP limits, and—when combined with software—enables automation for reporting and data collection.

8. Why is a strong business case critical?

Because it defines benefits before you start, creating accountability and making the process data-driven rather than based on vague promises in PowerPoint.

9. What is phasing and why does it matter?

Phasing allows partial funding for research or feasibility studies before full approval. It’s essential for balancing short-term delivery with longer-term innovation and R&D initiatives.

10. How do I measure success?

Track throughput, conversion rates, lead time, and gate cycle time (decision speed). Make “decision latency” a PMO KPI. Also monitor portfolio mix—BAU vs strategic vs R&D.
